I'm about to install a nitrous kit on my car and was wondering if I need to upgrade the pump or not. I made 397 whp and 377 wtrq cam only and would like to spray a 150 shot on it but I was going to start with a 100 shot. Should I wait to get a fuel pump before I do anything or should I be ok? Anybody got any insight on this? I searched but didn't find what I was looking for. I appreciate any and all help you guys could give me.

 

I would.

 

Well if I can get away without doing it then there's no need to spend the extra money. You know what I mean? I know its not much but I don't want to spend more than I have to. But I don't want to blow it up either.

 

Yes you will need one. You will have to fudge the tune, or run a big fuel pill to account for the drop in pressure. You can get a Racetronix kit for cheap and it installs in a snap.

 

^ Thanks man. That's what I figured. I was just kinda hoping. Is anybody using this one or do you think it would work : http://www.texas-speed.com/shop/item...d=225&catid=10
Thanks for the replies.

 

just get the racetronics kit- it is simply plug and play- especially if you are doing the job. If you are not doing it then whoever puts it in will appreciate you getting the racetronics kit.

I am waiting to put all the stuff on my car for this exact reason- fuel pump. I have everything else.

 

My pump maxed out at 400hp on a 100 shot so I dropped the Walbro 255 and no problems after that.

 

Hey rock, I would get a new pump. I have similar numbers to you but i already have a 100 shot setup. I have taken the bottle out until i install the new clutch and pump. Then i'll be able to spray

 

If any read my earlier post where I said I think the Walbro is plug and play. Its not. Just thought I would clear that up. Thanks for everybody's help.

 

Sent you a PM on this subject

 

another for the Racetronix kit. has its own feedwire/fuse to alternator

 

Yet another vote for Racetronix...very easily done.

 

Check out HSW for the Racetronic kits. i would do a pump. A couple write ups on fuel system upgrading in my web site. Also, the math for figuring when you need to upgrade based on HP needs.

We also stock racetronix kits on the shelf.
